To all whom it may concern:

Be it known that I, FERDINAND J. FELDT, a citizen of the United States, residing at Peoria, in the county of Peoria and State of Illinois, haveinvented certain new and useful Improvements in Seeding-Machines; and I do hereby declare that the following is a full, clear, and exact description 'of the invention, which will enable others skilled in the art to which it appertains to :make and use the same. i

This invention has reference to certain new and useful improvements in seeding machines, and relates particularly to the means employed for the transmsision of 'mo tion from a driving shaft adapted to operate suitable seeding devices within a hopper, and

vto distributers suitably disposed'to receive spur gears connecting the driving and counter-shafts; helical pinions carried on the upper ends of the distributing shafts; and gear wheels'on the counter-shaft in mesh with said helical pinions; said last men tioned gear wheels having teeth unlike the teeth of the helical pinions, but provided with a series of radially projected teeth, more in thenature of the teeth of a spur gear, except that the teeth have rounded'outer ends. The construction is such that the gears and pinions have more orless-of a sliding motion as the teeth move intofandout of mesh. l

That the'invention panying drawings, in which i Figure 1 is a view from the rear in elevation of so much of a broadcast distributing machine as will illustrate myimprovernents' which are attached thereto; Fi 2 is aside elevation viewed from the left and side of, Fig. 1 with the distributer device's omitted Fig. 3 is a vertical section enlarged through are may 'be morefully, understood reference is had-to the accomshaft; Fig. 4 is a top plan view enlarged ofone of the helical pinions, and Fig. 5 is an elevation of the gear shown in Fig. 4 and on the same scale.

Like numerals of reference indicate -corres onding parts throughout the figures. n the drawings I have shown my invention aslapplied to adouble fan distributer,

one of the gears on the counter-shaft which drives the helical pinion on the distributer' necessitating two distributing shafts and duplicate means on a driving shaft which cooperate therewith for actuating the said distributer. However, it is understood that the mechanismherein shown and described is equally as applicable to a'single distributer seeding machine as it is to a double fan distributer.

In the drawin s I have also illustrated "a preferred form 0 distributer, yet it is to be understood that the devices which I claim as my improvement may beapp'lied to other forms of machine than that here shown. I In the drawings 1 denotes a support'for the seeding devices consisting of 3 an end-gate,

which is of the usual type adapted to have a detachable connection with the rear of .a

suitable vehicle. I

2 refers to a hopper support in which is adaptedto be carried suitable seeding dc,-

up from and supported by the said hopper support.

The feeding devices to which me 5 vices (not shdwn) which may be of the usual force feed type or other suitable feeding means, and 3 denotes a hopper extending erencevhas been made, but not shown, are" aYiapted to be actuated bya transverse driving shaft .4 which passes through the hopper support 2 and is journaled in the bearing plates -5 attached thereto.

The driving shaft 4 is-adapted, when attaching the seeding devices to the vehicle, to be driventhrough suitable' connection with one of the ground wheels of the vehicle, or the same may be driven in any other desirable or convenient manner.-

Depending and diverging from the hopper support 2 and connecting with the feeding devices therein, are the feed spouts 6 which at their lower ends are connected and supwhich may be dprovided suitable openings, not shown, to'a apt any material discharged through the spouts 6 on to thefan distribu- 'ters' to be described.

'ported upon a plate" or shield 7, through be dischar ed; through the shield from the the degree of a tooth, it willleave. off where I In the drawings the teeth of the-gears 18 are 8 denotes, 'referably', apair of vertically disposed distributer'shafts 8, the lower ends. of which pass through the shield, 7 and are journaled in the bearings 9 su ported'by the said shield. The upper en s of the said shafts 8 pass through the bearings 10 which; project laterally from and are supported by the arms 11 which extend outwardly from the lower opposite sides of the hopper sup-. port 2. On the lower ends of the shafts beneath the shield are carried the fan distribu' ters 12 which are so disposed beneath the sh'ieldas to receive any material which may spouts 6, w ile on the extreme up er ends of the-said shafts are carried the helical-pinions 13. 1

1e denotes a transversely disposed counter s haft, which may be carried at the rear of or through the hopper support, which will serve as a bearing therefor, and the shaft is also journaled in a bracket l5 attached to I and projecting from the supporter end-gate 1. I

16 is a spur pinion carried by the drive shaft 14 which is continuously in mesh with a spur gear '17 carried on the driving shaft 4, through and by means of which the power which is transmitted to the shaft 4 will be imparted to the'couiiter-shaft l4. 1

' Carried by the counter-shaft 14 is a pair. ofgears 18 which arev adapted to intermesh withand drive the helical pinions 13, provided with teeth 19 extending radially rom the peripheral face of the gear and rounded on their outer ends to adapt the said teeth to have constant and perfect 00D." tact with the helical teeth of said .pinions 13.

shown as-ball-teeth, suitably spaced apart and projecting radially from the -gears.

- The advantages of the helical pinions and form of gears on the counter-shaft in mesh therewith as applied to broadcast seeding machines are numerous. The use of such gearing maintains a uniform driving contact at all times, and as the pinions are advanced the next tooth begins, thus presenting an approximately unbroken surface, which in ,sss

all times'and with the teeth of the gear and pinion sliding into and out of mesh.

The application of gearing of the character described for transmitting motion from a driving shaft of a seeding machine to the fan distributers thereof, provides a drive which is practically noiseless and simplifies the construction. -and arrangement of such parts; accomplishing all that is claimed for a friction drive without slipping and avoiding the use of all springs, also by their use is obviated the use ofmeans for yieldingly holding the gears in contact, such as a spring for reliev- ,ing the strain on the teeth when the ordinary bevel gearing is'thrown into mesh, which are used on a similar type of machine.

Having thus fully described my invention, what I claim and desire to secure by Letters, Patent of the United States, is:

Ina device of the class described, a sup porting member, a combined shield. and bracket extending laterally from said supporting member, a hopper support having a hopper extending from one end and feed spouts depending from the other end and connected to said shield and bracket, a drive shaft and a counter shaft journaled through said hopper support, arms extending from said support, hangers connected to said arms and provided with vertical shaft hearings in their free ends, shaft bearings carried by said shield and bracket in vertical alinement with the bearings of said hangers, vertical shafts carried by said shield and bracket bearings and by said hanger bearings, distributer devices carried by the lower ends of said vertical shafts and operating beneath said combined shield and bracket, pinions having obliquely disposed spaced teeth, gears carried by said. counter shaft and provi'ded with spaced semi-spherical peri ilicral teeth adapt- ;ed to engage the oblique teeth of said pmions, and means for transmitting the motion from said drive shaft to said counter shaft; r In testimony whereof I aiiix my signature, in presence of two witnesses. i
